I am puzzled Chipko when we have identical Aerotec/Suzuki 20 outfits that mine doesn't splash at all and yours does (even if an acceptable amount)??
It can only be our heavier (I think we are anyway) load... but why??
Crab catchers when I was choosing between the various new 20hp outboards I noticed in the dealers the water deflector plate (the smaller one above the main anti-ventilation plate) on the Honda 20 was quite small and I did wonder if that might allow more "Aerotec splash".
Have a look for Max's deflector plate too.
